Ben Clayton f1f56b2d3c tint/writer/glsl: Set default precision to highp
WGSL states that `f32` is a IEEE-754 binary32. mediump precision guarantees are much smaller than highp, and using mediump can break code generated by tint.

mix of ivec is not core until later GLSL versions.
Just polyfill in the writer with ternary ops.

Ben Clayton 77a90cb796 test/tint/builtins/gen: Use returned value
It appears that FXC and DXC do some validation post dead-code-elimination.
These tests have been updated so that the return value is assigned to a storage buffer, ensuring that all validation is performed.

Many DXC tests are affected by https://github.com/microsoft/DirectXShaderCompiler/issues/5082, which have been SKIP'ed.

Ben Clayton 03de0e83ae Move tint::transform::Robustness to a santizier transform
There's no good reason for this to be public.
Move it into the writers, and expose a 'disable_robustness' option to
turn it off. This can be expanded to hold more fine-grain control in the
future.

Ben Clayton be367b73ae Reduce shader complexity for external textures
Do more math on the CPU to avoid per-fragment ALU operations.
Use a mat3x2 instead of mat2x3 to avoid padding.

Stephen White 05d8b02b0f GLSL: implement host-visible memory padding.
Since GLSL ES does not support the offset= attribute, struct members
with explicit @align or @size attributes require adding explicit
padding members.  This in turn requires rewriting any constructor
calls to initialize the new padding to zero, handled in the same
transform.

Note that this is currently overly-verbose, and will add padding where
GLSL doesn't technically need it (e.g., padding a vec3 out to 16 bytes).

Stephen White 863d9edf59 GLSL: Change Add[Spirv]BlockAttribute to support GLSL
Modify the AddSpirvBlockAttribute transform to fix top-level structure
access of uniform, storage and push-constant buffers for use in the
GLSL backend. The small change to the transform makes the transform
wrap host-sharable buffers, if they're also used as a
non-host-sharable structure. Also rename the transform to
AddBlockAttrbibute in order to reflect its wider applicability.
